I run the 165 navigator...being it is only about 8 inches shorter than your boat and 3 inches narrower, it is pretty darn close in spec.
First question I would have for you is this: Where did they mount the motor? All the way down tight to the transom or 1 bolt up? My guess is the motor is mounted one hole up... I have no doubt you can move that motor all the way to the highest mounting hole to begin with if you stay stainless...
The next question is what stainless prop did they put on it? With that set-up, I am guess a 19 pitch will be close and hopefully a good cupped performance 19 pitch at that... Not sure what the gear ratio is on that motor, but I do believe you are low on RPMs as well.
The moving of the motor is a move-and-test situation, to find a good balance. No matter what you do, there are trade offs and limiting factors as to what the rig is capable of doing. With my rig (90 hp yamaha) I ended up going with a 17 pitch ballistic prop, and a 4 inch manual setback plate to raise the motor up even higher... I suffer just a touch in handling/turning moderately at WOT, and at mid speeds I have to trim down a little to stay hooked up on turns as well...nothing we shouldn't be doing already to keep the boat under control, though...
I'm betting a good 19 pitch with the motor raised will get you real close...
